Might get introuble but I chopped up a boomy barrel and a pe barrel. Lined it up welded it together and made sure the inside was flush.
I could of use the lathe but I did not want to spend that much time on it
Since I purchase the barrels wanted a tru one of a kind cf barrel

Wow that's putting in some serious effort for a cf barrel. Good job on the initiative. How is the thing on the inside? I would think that short of having a custom one piece adapter made a wielded one wouldn't be ideal due to the seam.
